Aleri, JW, Nguhiu-Mwangi J, Mogoa EGM.  2012.  Welfare of dairy cattle in the smallholder (zero-grazing) production systems in Nairobi and its environs. AbstractWebsite

Animal welfare is defined as the ability of an animal to interact comfortably with its environment through its physiological, psychological and behavioural systems. About 70% of dairy production in Kenya is from the smallholder production systems. These production systems are negatively impacted by a number of factors including poor nutrition, substandard husbandry and management practices, lack of appropriate farm inputs, diseases and low incomes. These factors influence the welfare of dairy cattle, hence their importance for its evaluation. This study was therefore designed with the following objectives: 1. to determine the welfare of dairy cattle in the smallholder production units in Nairobi and its environs, 2. to determine the risk factors contributing to poor welfare of dairy cattle in the smallholder production units, 3. to determine the indicators of poor welfare of dairy cattle in the smallholder production units, 4. to determine the farmers’ and stockmen’s perspectives of animal welfare. These objectives were achieved through a cross-sectional study carried out in 80 smallholder dairy units purposively selected in Nairobi and its environs, in which 306 dairy cows were examined. The welfare of cattle in these dairy units was evaluated through several methods which included: visual observations for animal- and farm-level factors that indicate poor welfare of cattle; taking measurements of dairy housing unit dimensions such as cubicle, walk-alley, kerb and feeding bunk; and using a structured questionnaire to interview farmers and stockmen on nutritional regimes and other management practices such as removal of slurry, milking techniques, record keeping and disease control. These factors were recorded and later analyzed. Analyses included descriptive statistics, and simple associations using chi-square at p< 0.05 significance level. Over 80% of these smallholder units had factors that contributed to poor welfare of dairy cattle. These factors included under-size cubicles, small walk-alleys, too high feeding bunks with traumatic edges, too low positioning of neck rails at the feed bunks, sharp objects and edges within the housing units and dilapidated housing structures. The main evidence of poor welfare was injuries on the animals. The body condition score (BCS) of the cows was the main indicator of welfare relating to feeding. Presence of injuries or scars on the skin at various parts of the body was considered a positive indicator of poor welfare either associated with housing structures, management practices or animal interactions. Other causes of poor welfare of the cows were hind-limb tying during milking, teat pulling during hand-milking, more than 24-hour delay before sick cows were treated, and mixing of cattle of different age-groups in the same compartment. Cow-human interaction was poor as evidenced by fearful response and long avoidance distance. This study concludes that poor welfare of dairy cattle exists in all the smallholder units evaluated, which is mainly caused by improper housing and management. Training of farmers and stockmen on animal welfare issues would therefore be a prerequisite to the improvement of dairy cattle welfare. Research on the physiological response to poor welfare of dairy cows in the smallholder units needs to be carried out to enhance the understanding of the impact of these risk factors on smallholder dairy animals.

Abstract: A case of acute respiratory distress syndrome due to babesiosis is reported in a 5 years old male Japanese sptiz. The patient was noticed to have developed sudden dyspnoea. The main presenting clinical signs included laboured breathing, broad-base stance but preferred recumbency, pallour and seizures. Blood smears from the ear tips revealed presence of multiple Babesia parasites in the erythrocytes. Hematology results showed slight leucocytosis, severe anemia and thrombocytopenia. Additionally, urinalysis revealed renal pathology and presence of leucocytes in urine. Despite aggressive measures to stabilize the patient, it died within an hour. Autopsy results also confirmed Babesiosis with generalized icterus.

A twenty year retrospective study was carried out in the Small Animal Clinic, University of Nairobi, Kenya and in a private Small Animal Clinic in Nairobi between the years 1988 to 2008. A total of 6548 bitches had been presented with reproductive problems. The cases were categorically grouped according to the type of infertility diagnosed. Non-infectious infertilities were sixty nine percent and infectious types were thirty one percent. Only two percent of the latter were confirmed in one clinic. 23.20 % of non-infectious infertility were managerial, 29.1% anatomical and 7.80% physiological types while 39.80 % were unclassified miscellaneous cases. The cases classified under infectious infertility consisted of; vaginitis/endometritis/metritis (36.3%), pyometra (25.3%), abortions (21.5%), vaginal discharges (11.7%) and miscarriages (5.1%). The incidence of infertilities was highly common in breeds of German shepherd (39%), Doberman (6%), Rottweiler (12%) and their crosses (43%). The percentage of the reproductive cases presented in both clinics had no statistical difference at (p<0.05). It was evident from the results of this study that infectious infertility exists among the bitches in Kenya and it would be beneficial to do further studies to establish the causative agents to avert any possible outbreaks of zoonotic diseases.
